ABSTRACT

A new and distinct variety of  Anthurium  plant named ‘ANTHDUNDAL’ particularly characterized by having bright red, cordate spathes, white, short spadix, very rich shoot formation, a very compact plant habit and dark green foliage, is disclosed.

GENUS AND SPECIES

Anthurium andreanum L.

VARIETY DENOMINATION

‘ANTHDUNDAL’

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct variety of Anthurium,botanically known as Anthurium andreanum L., and hereinafter referred toby the variety name ‘ANTHDUNDAL’. The new variety originated from ahybridization made in January 2006 in Bleiswijk, The Netherlands. Thefemale parent is a red Anthurium pot plant designated ‘4110-03’(unpatented), and the male parent was a red Anthurium plant designated‘5442-01’ (unpatented).

A single plant was selected in February 2007 and has been asexuallyreproduced repeatedly by tissue culture in Bleiswijk, The Netherlandsover a seven-year period. The present invention has been found to retainits distinctive characteristics through successive asexual propagations.

Plant Breeder's Rights for this variety have been applied for in Europeon Nov. 19, 2012. ‘ANTHDUNDAL’ has not been made publicly available orsold anywhere in the world more than one year prior to the filing ofthis application.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishingcharacteristics of this new variety when grown under normalhorticultural practices in Bleiswijk, The Netherlands.

1) Bright red, cordate spathe;

2) White, short spadix;

3) Very rich shoot formation;

4) Very compact plant habit; and

5) Dark green foliage.

DESCRIPTION OF THE NEW VARIETY

The following detailed description sets forth the distinctivecharacteristics of ‘ANTHDUNDAL’. The data which define thesecharacteristics were collected from asexual reproductions carried out inBleiswijk, The Netherlands. The plant history was taken on 45-week oldplants which were planted from tissue culture in 12-centimeter pots andgrown in a glass greenhouse between 19° C. and 24° C. Observations weremade in November 2014. Color readings were taken under 5000 lux naturallight in the greenhouse. Color references are primarily to The R.H.S.Colour Chart of The Royal Horticultural Society of London (R.H.S.)(2001).

After this period the spathe is limp            and dies. The small lobes very slowly accumulate some            chlorophyll. The lobes very slowly become green (RHS 146A).-   Peduncle:    -   -   Shape.—Erect.        -   Cross-section.—Round.        -   Length.—14.0 cm to 20.0 cm.        -   Diameter.—0.3 cm to 0.4 cm.        -   Color.—RHS 152C at unrolling of spathe, slowly turning RHS            146B when the spathe matures.-   Flowering time:    -   -   General.—One small rooted untreated tissue culture plant of            2.0 cm tall will flower after 4 to 6 months, depending on            the season, and 3 to 4 blossoms will appear. More blossoms            appear after some additional weeks so that a full flowering            and commercial plant will have 7 to 9 red spathes. Smaller            blossoms may occur on less mature plants.-   Spadix:    -   -   Size.—Length: 2.0 cm to 3.0 cm (depending on flower size)            Width (at apex): 0.5 cm to 0.6 cm Width (at base): 0.6 cm to            0.8 cm.        -   Shape.—Columnar.        -   Angle from spadix tip to peduncle.—180 degrees (spadix is in            one line with peduncle).        -   Texture.—When the spathe is unfurling the spadix is smooth.            When the spadix matures, small stigmata protrude. The            stigmata are evenly distributed round the spadix. The spadix            matures from base to top, slowly giving the spadix a            somewhat rough appearance.        -   Color.—Immature: RHS 15B Mature: RHS 158B Ages to: RHS 151A.-   Flowers:    -   -   Quantity per spadix.—100 to 180.        -   Spadix flower arrangement.—Bisexual, rounded in            cross-section.        -   Shape.—Rounded.        -   Size.—Length: 0.05 cm to 0.1 cm Diameter (maximum): 0.1 cm.        -   Color.—RHS 158B.-   Reproductive organs:    -   -   Stamens.—Not visible.        -   Pollen amount.—Very few.        -   Pollen color.—RHS 156D.        -   Pistil.—Quantity: Many Length: Less than 0.01 cm Color: RHS            156D.        -   Style.—Not observed.        -   Stigma.—Shape: Ovoid Diameter: Less than 0.01 cm Color: RHS            158B.        -   Ovary.—Rarely visible.        -   Ovary color.—Not measured.-   Fruit and seed set: None observed

COMPARISON WITH PARENTAL AND COMMERCIAL VARIETIES

‘ANTHDUNDAL’ differs from the female parent plant ‘4110-03’ (unpatented)in that ‘ANTHDUNDAL’ has a darker green leaf blade with more shine and adarker red spathe color, whereas ‘4110-03’ has a lighter green leafblade with less shine and a brighter red spathe color. In addition,‘ANTHDUNDAL’ has a smaller angle between spadix and spathe, whereas‘4110-03’ has a bigger angle between spadix and spathe.

‘ANTHDUNDAL’ differs from male parent plant ‘5442-01’ (unpatented) inthat ‘ANTHDUNDAL’ has a shorter spadix and a darker red spathe color,whereas ‘5442-01’ has a longer spadix and a brighter red spathe color.In addition, ‘ANTHDUNDAL’ has a leaf blade that is less ellipticalcordate, whereas ‘5442-01’ has a leaf blade that is more ellipticalcordate.

‘ANTHDUNDAL’ differs from commercial variety ‘ANTHEPEDI’ (U.S. PlantPat. No. 18,644) in that ‘ANTHDUNDAL’ has a smaller spadix width at thebase and a smaller mature leaf size than ‘ANTHEPEDI’. In addition,‘ANTHDUNDAL’ has along elliptical cordate shaped leaf blade, whereas‘ANTHEPEDI’ has a cordate shaped leaf blade.

‘ANTHDUNDAL’ differs from commercial variety ‘ANTHCOZAM’ (unpatented) inthat ‘ANTHDUNDAL’ has a larger spadix width at the base and a largermature leaf size than ‘ANTHCOZAM’. In addition, ‘ANTHDUNDAL’ has a longelliptical cordate shaped leaf blade and a red spathe, whereas‘ANTHCOZAM’ has an elliptical cordate shaped leaf blade and a dark redspathe.

I claim:
 1. A new and distinct variety of Anthurium plant named‘ANTHDUNDAL’, substantially as illustrated and described herein.
